Design, analysis, and implementation of a new high‐gain P‐type step‐up dc/dc converter with continuous input current and common ground

Abstract Step‐up converters are increasingly developed for renewable energy and storage systems in order to raise the output voltage of those resources to higher voltage levels. Conventional step‐up structures, such as P‐type boost converter, provide low voltage gain, and they must be cascaded with the same modules to produce higher boost factors. This conversion method reduces overall efficiency. Affording higher gains with lower duty cycles and single‐stage conversion increase efficiency. This paper proposes a new step‐up P‐type dc/dc converter with high voltage gain even with lower duty ratios. Additionally, it has continuous input current, high efficiency, and common ground between the input and the output. Detailed analysis is presented, and the performance of this new topology is compared with other high‐gain step‐up converters. Simulations and experiments evaluate the achievements of this topology. Results prove the proposed structure
